Done Hail 3 in 5 minutes,
although I'm 99% sure it works with four... Yes it does work in four, and here's the proof with a replay.
Just to let you know, As so many of you hate this level, I'm on the contrary and I love this level!
It's all because of the huge skill amounts combined with the low save requirements. It if wasn't like that, I wouldn't enjoy the level either.
